In step 303, hole drilling type sample is generated based on the predetermined profile for the tunnel section that will be drilled and route.Drilling
Style can be generated essentially according to any technology in the various known technologies for generating drilling style, but according to this hair
Bright embodiment, generate drill style when it is also contemplated that in terms of other.
In general, when generating drilling style, it be close to the hole that the periphery of rock surface drills out by about possible Kong Fang
To limitation.This is because the intrinsic diameter/size of drilling machine/feed beam.That is, it is impossible to outside exactly along profile
Shape drilling, but must drill relative to desired orientation gently towards other places, to drill out next round after epicycle explosion
Kong Shiwei drilling machine/feed beam vacating space.This is known per se, and General Principle is shown in FIG. 4, in Fig. 4,
In, the desired width in the tunnel to be drilled is indicated with a, wherein actual borehole is represented as sawtooth form 401, wherein distance b
Substantially by drilling machine/feed beam size Control, and wherein, distance b ensures that tunnel can be kept in subsequent passes
Width.That is, this, which may to drill in next round, becomes difficult if making distance b become smaller in a wheel, so that
Drilling will for example be guided more outward because space limits.Fig. 4 illustrates only General Principle, and outside angle c can be with
Any appropriate ways for generally attempting the overcrushing of limitation rock determine, wherein outside angle c can take turns from one to another
One wheel variation.
However, embodiment according to the present invention, the other parameters other than the limitation of Fig. 4 are taken into account.Therefore,
When generating drilling style with the step 303 in Fig. 3, also contemplates when generating and drilling style and applied by the part of excavation in tunnel
The limitation of the navigability of rear end 209B, 210B, the 211B about feed beam 209 to 211 added.The excavation part in tunnel
Tunnel wall the manipulation of the possibility of the feed beam to drilling machine is applied into limitation so that from excavate in terms of angle by expectation drill out for example with
It may can not actually be drilled out due to the limitation of feeding beam space with reducing the hole of the amount for the extra rock being mined, this may be caused
Make feed beam in order to can not be carried out according to identified drilling style come the required manipulation to drill.For example, when the hole to be drilled out
When narrowing and/or when hole is not along straight line, it may is that.
When generating drilling style, the hole that expectation drills out can be checked, once have determined that the hole to be drilled out, Huo Zhe
Generate complete drilling style --- wherein, discovery hole is inappropriate from the point of view of drillability --- later, then it can weigh
The new step 304 determined about navigability.This, which may cause such as hole, with other direction and may be had different
The hole of hole length is substituted.Iteration can be executed, until all holes in step 304 are considered as can drilling out,
In this case this method terminates in step 305.Then it can be drilled according to identified drilling style to rock face.
Therefore, following drilling styles can be generated in embodiment according to the present invention: the drilling style will can be drilled
, and the drilling style can not be subjected to manipulation difficulty because of the country rock not being taken into account.In this way it is possible to ensure rock
Stone is mined the degree for being enough to provide desired hole, at the same can by create will dominate at the position of rock face about
The drilling style that the physical condition of the navigability of feed beam is taken into account reduces the broken of extra rock, so that creation can be with
Cause the extra rock being mined drilling style more less than other possible situations.Embodiment according to the present invention, it is disclosed
Method in profile variations, particularly narrow and/or tunnel bending or tunnel Curvature varying section in may be most
Beneficial.
Embodiment according to the present invention, such as basis of the tunnel in tunnel coordinate system is above such as by tunnel line TL and phase
The expression that associated profile determines for determined when generating and drilling style feed beam possible navigability and it is thus determined that
The drillability in hole.That is, can use the hole for assuming to have excavated the face to be drilled, wherein can be for example using root
The 3D that the hole of hypothesis is obtained according to interpolation above is indicated.
Embodiment according to the present invention, in the drillability for determining hole, tunnel excavated part with to be drilled
The profile that face apart corresponds roughly to the distance of feeding beam length is determined for about feed beam away from boring direction
The limitation of the navigability of end.
Embodiment according to the present invention alternatively determines the drillability in the hole of drilling style using practical palisades.This
It can be for example by being realized with excavation process scanning palisades.Due to being frequently present of the overcrushing of rock, this can be into one
Step provides feed beam dirigibility, so that may be considered as the hole that can not be drilled out using the theoretical extension in hole may be actually
It is still that can drill out.
In addition, embodiments of the present invention are related to the specific method for generating drilling style, this method will be about feeding
The limitation of the navigability of beam is taken into account.
Therefore, hereinafter, by the creation for being used to generate drilling style of the embodiment according to the present invention of diagrammatic illustration 5
Property method 500.Fig. 6 to Figure 12 will be referred to further to illustrate this method.
The tunnel line TL similar with the tunnel line of Figure 1A is shown in FIG. 6, but furthermore also shows tunnel in Fig. 6
Expectation shape 601 seen from above.Further there is illustrated the practical palisades 602 for having excavated part in tunnel, including with digging
Driving is about to the rock face 603 to be drilled.As having been discussed above, tunnel line point is defined on the coordinate system used in excavating
In, and in this example, drilling has arrived at the point between TLn and TLn+1.Even if may have before tunnelling starts
The intention of the drilling of continuous round is carried out at continuous tunnel point, it can not be according to the hole drilling type planned in advance but drilling is possibly
Sample accurately carries out, it is expected that the drilling of every wheel and explosion all reach the next of tunnel line TL in the drilling style planned in advance
A tunnel line point.For example, explosion possibly can not be crushed the complete length to portal and/or may be for example due to more porous
Rock and keep the major part of rock broken.However, embodiment according to the present invention, only to be drilled once having determined
In the case where the position of rock face establish be used for next round drilling style, and the drilling style independently of with tunnel line point phase
The current schedules of pass.
Illustrative methods in Fig. 5 start in step 501, in step 501, similar with the method for Fig. 3, it is determined whether
Determine drilling style.In this case, this method proceeds to step 502, in step 502 the determination current rock to be drilled
The facial contour FC in stone face.Facial contour FC determines that the plane indicates navigation plane NP in general herein for plane,
According to length, the direction etc. in the plane determination hole to be drilled out.As seen from Figure 6, the rock that is obtained by previous shot
Face 603 is non-uniform and can change significantly.Navigation plane NP can be determined, so that navigation plane NP is substantially or complete
The rock face 603 to be drilled is not included entirely, but navigation plane NP can also be arranged to and 603 part of rock face to be drilled
Ground fully intersects.
Navigation plane NP can be limited in various ways, and according to this example, navigation plane NP is defined such that it
It is vertical with line, the i.e. dotted line 605 of the wheel expection boring direction to be drilled is indicated.As in this example, it is contemplated that drilling side
To can be with direction difference of the tunnel line TL at the point that tunnel line TL and navigation plane NP intersects.For example, boring direction can be with
It is determined by the line 605 for point and tunnel line the TL intersection intersected in tunnel line TL with navigation plane NP, and wherein, line 605
Intersect with point 604 and tunnel line TL of the navigation plane NP at certain suitable distance.From navigation plane NP to point 604 away from
From can correspond to or correspond roughly to generate drilling style round in the longest hole length to be drilled out.From navigation plane NP
Distance to point 604 is also possible to any other suitable distance more than or less than the longest hole length to be drilled out in the wheel.
For example, the distance for example can be set or be changed according to preset value by operator in the case where needing to change boring direction,
And in this case navigation plane can be automatically regulated to be for example perpendicular to boring direction.In this example, navigation plane
Therefore NP is determined to be so that line 605 is perpendicular to navigation plane NP.Therefore, navigation plane NP is independently of the rock face to be drilled
603 overall appearance and limit, and navigation plane NP does not need to be parallel to the rock face 603 for example, but can be relative to
Practical rock face is significantly at an angle of.
Navigation plane NP can also be limited independently of boring direction and substantially can be relative to such as tunnel line TL
And/or boring direction 605 and/or rock face have any suitable angle.Exist in the art for determining navigation plane
The various methods of NP, and any such method can be used.For example, navigation plane NP can be arranged to for example by drilling machine
The other staff of the generation of operator and/or participation drilling style determine.Additionally, it is contemplated that boring direction can be according to any suitable
Standard define and can have any suitable direction, and therefore do not need to use tunnel according to described herein
The example of diatom point defines.
Facial contour FC determines that in navigation plane NP, facial contour FC can be according to these tunnel wheels in navigation plane NP
Exterior feature whether in the same plane and by being determined as described above using 2D the or 3D interpolation of the tunnel contour of TLn and TLn+1,
To obtain the facial contour in navigation plane NP.The tunnel line profile of adjacent tunnel line point can be in shape from a tunnel line point
To another tunnel line point different --- for example, in the case where tunnel narrows or otherwise changes shape --- and can
For example to be defined in different planes by the Curvature varying in such as this example, in this example, tunnel line point TLn and
The tunnel line profile of TLn+1 is also in different planes relative to navigation plane NP.Therefore navigation plane NP do not need and
It is not vertical with tunnel line in intersection according to this example, and therefore, even if adjacent tunnel line point TLn and TLn+1
Tunnel contour is identical, and facial contour FC is also different from tunnel line profile.When the condition for generating drilling style is taken turns from one to another
When taking turns different, particularly when tunnel narrow and/or tunnel bending or tunnel curature variation when, illustrative methods may be
It is best.
This method then continues to step 503, in step 503, determines bottom profile in a similar way as described above
BC0.Bottom profile BC0 determines that bottom plane BP is the plane being separated by a certain distance with facial contour FC in bottom plane BP.Bottom
Facial planes can be defined as to be located at facial contour FC at a distance from for example being limited by above-mentioned line 605, and therefore be located at
The longest for apart for example corresponding to facial contour FC or corresponding roughly to the hole to be drilled out in the round for generating drilling planning is long
At the distance of degree.Bottom plane BP can also be arranged to be located at facial contour FC at a distance of any other it is greater or lesser at a distance from
Place.The position of bottom plane BP can also be arranged to needing for example to extend or reduce facial contour/navigation by the operator of drilling machine
For example by changing the preset distance between facial contour and bottom plane in the case where the distance between plane and bottom plane BP
To adjust.Therefore, the distance between facial contour and bottom plane can be more than the longest hole length to be drilled out.In addition, in plane
In the case where at an angle relative to each other, even if being for example equal to the longest hole length to be drilled out, plane along the distance of tunnel line
The distance between will be changed according to the position that measures in the plane, and therefore the distance can be greater than and might be less that
The longest hole length to be drilled out.Bottom plane BP and bottom profile BC0 therefore can be arranged in the intersection position with tunnel line T
Set, at the point 604 i.e. in this example perpendicular to tunnel line T.Bottom plane BP can alternatively be arranged perpendicularly to line 605 simultaneously
It is accordingly parallel to navigation plane NP.Bottom plane can also limit in any other suitable.Bottom profile BC0 can make
With being determined in this case using 2D the or 3D interpolation of tunnel line point TLn+1, TLn+2.
In step 504, it establishes another profile, limit profile LC.Limitation profile LC also uses adjacent tunnel line wheel
Wide TLn-2, TLn-1 in a manner that is similar to the above with facial contour FC at a distance and from facial contour FC with
Interpolation forms on the opposite direction of boring direction.The distance between facial contour FC and limitation profile LC can be such as being selected as
In the length of the feed beam of drilling machine.According to above, limitation profile LC for the country rock for having excavated part in tunnel to be taken into account,
To determine the drillability in hole when determining drilling style, so that the navigability of feed beam be taken into account.
Tunnel line profile can be used to carry out interpolation to limitation profile LC as described above, but if the drilling in tunnel
The scanning of partial practical palisades indicates available, then can alternatively be indicated using the scanning to mention when determining whether hole can bore
In high precision.Furthermore, it is possible to which it is consistent with navigation direction that limitation profile LC is chosen to its normal vector, and therefore limitation wheel
Wide LC is parallel to facial contour FC.
According to this illustrative methods for generating drilling style in the current position of drilling machine, by being directed to facial contour FC
Different piece generate individually drilling style and form the drilling style comprising the facial contour FC to be drilled.Therefore, in step
In 505, the first largest contours MC0 is generated.Largest contours MC0 indicate facial contour FC maximum possible part, the maximum can
In energy part, the hole with the maximum length drilled out can be drilled out during tunnelling, while ensuring manipulating for feed beam
Property.Largest contours MC0 is arranged in navigation plane NP, i.e., is in same plane with facial contour FC.Due to facial contour FC
It is the maximum surface to be drilled, therefore the boundary of largest contours MC0 is limited by the periphery of facial contour FC, but MC0 also passes through and makes
It is defined with the 3D interpolation of limitation profile LC and bottom profile BC0 in the plane of facial contour FC.This is shown in FIG. 7 by dotted line
Interpolation line 701 and 702 is shown.Also the gained profile MC0 defined by facial contour FC is shown as the hatched area of Fig. 8, therefore,
Fig. 8 shows facial contour FC and identified MC0.Therefore, region MC0 indicate facial contour FC can when carrying out next round drilling
To drill out the part in the hole of complete length.Region, the i.e. hatched area 801 being located at outside facial contour FC generated by interpolation
It is ignored because the region will be without drilling.
When according to it is above-mentioned largest contours MC0 has been determined when, for largest contours MC0 generate drilling style, that is, walk
Rapid 506, the drilling style therefore constitute will from facial contour FC to bottom profile BC0 the hole drilled out drilling style.In basis
All profiles hereafter can not generate the drilling style for largest contours MC0 alternatively before having been established.That is,
Each profile is initially set up, then generates drilling style for the various pieces of facial contour.The drilling style of largest contours MC0 can
To be generated according to any proper method for generating the drilling style to drill to the profile towards bottom profile,
In, various methods are well known in the art.Since largest contours MC0 does not include entire facial contour FC, largest contours
The drilling style of MC0 would not indicate the total volume for the simultaneously explosion that drill during the round to be drilled.Additional brill must be added
Hole is to drill out complete volume.Therefore, the remainder of facial contour, be shown as band in Fig. 9 and hacures and be expressed as
DC, Fig. 8 non-shadow line part still wants drilled, but may can not use because the navigability of feed beam limits
The hole of whole length, but maximum length of the length less than the hole for the round to be drilled can be used for this part of facial contour
Hole.
Therefore, in step 507, it is determined that constitute the difference surface, i.e. of the difference between facial contour FC and largest contours MC0
Profile DC.About the surface, will generate its mesoporous when drilling out the drilling style of largest contours MC0 generated will be drilled out than
The drilling style of the shorter length in the hole drilled out.
It is thus determined that the number of rows in the hole to be drilled out on difference profile DC.This can be for example using in generation drilling style
When the rule to be used about the distance between hole establish, wherein the distance can be for example depending on the rock to be drilled
Property, diameter, the length of rock section that will be excavated in epicycle in the hole to be drilled out etc., as known per se.So
And this determination about hole usually has been carried out and is not therefore a part of the invention.Therefore, for example in establishment
Applicable hole apart from while can also determine the number of rows in the hole to be drilled out in difference profile DC.
Then, it is established using the width of the number of rows in the identified hole to be drilled out and/or alternative difference profile DC
The number n for the central bottom profile BC1 ... BCn to be used between facial contour FC and original bottom profile BC0, i.e. step
507.For example, can be directed to, the every row that for example drill out in difference profile DC vertically be arranged or the hole of horizontal row generates a bottom
Profile.Central bottom profile BC1 ... BCn can be generated in a manner of identical with BC0 above, i.e., by using adjacent tunnel
The interpolation of the tunnel contour of line point generates.About the position of bottom profile BC1 ... BCn, these bottom profiles can be arranged
It is evenly spaced apart between facial contour FC and bottom profile BC0.That is, for example, being added if only to generate one
Drill style, then additional bottom profile BC1 can be arranged to be located in the half-distance from facial contour FC to bottom profile BC0
Place.It can also determine in any other suitable to additional bottom profile/plane distance, for example, according to be drilled out
The curvature in hole determines.
According to this example, two additional bottoms being evenly spaced apart between facial contour FC and bottom profile BC0 are generated
Contouring BC1, BC2.This is shown in FIG. 10, and two mid-planes BC1, BC2 are shown in FIG. 10.Also can be used in addition to
Other distributions between profile except equidistance.Then drilling can be generated for each additional bottom profile BC1 ... BCn
Style, i.e. step 508, wherein above-mentioned principle can be used, by taking turns respectively to additional bottom profile BC1 ... BC2 and limitation
Wide LC carries out interpolation in the plane of facial contour to generate additional drilling style, and additional drilling style by facial contour FC into one
Step defines.This is shown in Figure 10 as the line 1001,1002 used in interpolation, and to get into the hole depth defined by BC1
Part the part MC1 of DC is schematically illustrated as in Fig. 9, and to get into and be existed by the part of the BC2 hole depth defined
The part MC2 of DC is schematically illustrated as in Fig. 9.The part for having generated drilling style of facial contour FC, such as MC0 are neglected
Slightly.As mentioned above, the drilling style for MC0 can be generated after having determined that part MC1, MC2.Therefore, work as life
When at drilling style for BC1, according to this example, this will make the holes of other rows of row or more to be drilled out substantially have
There is the length for corresponding to the distance between facial contour FC and central bottom profile BC1.Again, about facial contour FC
The hole for generating the part of drilling style is ignored.In addition, with hole for example too close for the hole of largest contours MC0 planned
It can also be ignored, reason is that the hole planned usually will be the hole with long length.Alternatively, can alternatively from
Such hole is saved in the drilling style of MC0.
When having generated the drilling style for the first central bottom profile BC1, it is directed in second in a similar way
Between bottom profile BC2 generate drilling style, this in this example will make row or more other row the hole to be drilled out it is basic
The upper length with corresponding to the distance between facial contour FC and the second central bottom profile BC2, i.e., with the hole of more short length.
Other than hole related with the part of style that drills about bottom profile BC0 generation of facial contour FC, used in first
Between the hole of drilling style of bottom profile BC1 be also ignored, and the hole for being too near to the hole planned as described above is also neglected
Slightly.
Therefore, it when being directed to bottom profile BC and intermediate profile BC1, BC2 generates drilling style, has generated and has covered
The aggregation type drilling style of entire facial contour FC is covered, and Figure 11 passes through the solid line extended respectively from facial contour FC to bottom profile
Schematically show the hole to be drilled out.Then aggregation type drilling style can once drill out a drilling style or be used as
Individual aggregation type drilling style, i.e. step 509, wherein can drill in any order, rather than once only drill out a brill
Hole style.Then this method terminates in step 510.
Drilling style about different bottom profiles can also be still sequentially generated for identical region with any other,
But be advantageous if it is considered to for example reducing extra rock, then shorter hole can be kept in borderline region rather than longer
Hole.Furthermore, it is possible to determine different part MC0, MC1 etc. before determining actual borehole style.
In addition, embodiment according to the present invention, can expand the area of facial contour FC not covered by largest contours MC0
Domain, it can reduce the region of MC0.This can for example be in the case where difference profile is determined to be too small for example too narrow
The hole vacating space of other rows of one row or more.Such parameter can be preset in the controls.
Expanding for diff area can be realized by reducing the size of largest contours MC0.For example, profile can will be limited
LC projects the facial contour FC into navigation plane, rather than utilizes interpolation, to further limit the size of largest contours MC0.
This is illustrated in Fig. 7 by dotted line 710, this is so that largest contours MC0 becomes smaller, so that shorter hole length will be used by increasing
Come the region to drill.
Projection can be applied in combination with according to interpolation above, but projection also can be used and replace interpolation.That is,
For example, limitation profile LC or bottom profile BC0 can be used only in the foundation of largest contours MC0/ difference profile.Therefore, root
According to embodiments of the present invention, bottom profile BC0 or limitation profile LC is only determined in the method for Fig. 5.
According to above example, the projection on bottom profile BC0 to facial contour FC may not apply any essence difference.So
And according to other situations, it say like that situation shown in Figure 12, may be suitble to take turns using bottom profile BC0 to face
Projection on wide FC.
Figure 12 shows the case where tunnel narrows, i.e. tunnel/hole transits to relatively narrow section from wider part section.Line 1201 illustrates
According to interpolation above, which causes largest contours MC0 to have the width corresponding to line 1203.According to disclosed in Figure 12
Example, largest contours MC0 can be reduced using interpolation by projecting to bottom profile BC0 on facial contour FC.
This is shown by line 1202, and line 1202 indicates the projection on bottom profile BC0 to facial contour FC and leads to most bull wheel
Wide MC0 has the smaller width indicated by the line 1204 in figure.This increase in turn facial contour FC to drill out have subtract
The part in the hole of small length, the increase of difference profile, the i.e. reduction of largest contours MC0 are indicated by line 1205.
Finally, for simplicity, bottom profile BC0, BC1, BC2 have been shown as at least substantially flat table
Face.Such case is needed not be, but any profile or whole profiles in bottom profile can use any desired shape.
In addition, the method for generating drilling style is described above, this method will be to rock face by being present in
Drilling machine at the position to drill executes.The generation of embodiment according to the present invention, the style that drills can be by computer example
It is such as executed in planning center, in planning center, such as drilling style can be generated for any position in the hole to be drilled,
So that personnel, which can for example assess drilling style generated and adjust, to input parameter used in the generation of style drilling.
